Picking your nose is even grosser than you thought & More Latest News Here – Up Jobs

We’re scientists who have researched the environmental contaminants — in our homes, our workplaces, our gardens — so we have some insight on what you’re really jamming up there when your finger is slotted satisfyingly into your sniffer.

Nose picking is a natural habit — children who have not yet learned social norms realize early on that the fit between their forefinger and a nostril is pretty good. But there is lot more than just snot up there.

Tinnitus afflicts about 749 million people worldwide

During the approximately 22,000 breath cycles per day, the booger-forming mucus up there forms a critical biological filter to capture dust and allergens before they penetrate our airways, where they may cause inflammation, asthma and other long-term pulmonary issues.

Cells in your nasal passage called goblet cells (named after their cuplike appearance) generate mucus to trap viruses, bacteria and dust containing potentially harmful substances such as lead, asbestos and pollen.

Nasal mucus and its antibodies and enzymes are the body’s front line immune defense system against infections.

The nasal cavity also has its own microbiome. Sometimes these natural populations can be disturbed, leading to various conditions such as rhinitis. But in general, our nose microbes help repel invaders, fighting them on a mucus battlefield.

The dust, microbes and allergens captured in your mucus eventually get ingested as that mucus drips down your throat.

This is typically not an issue, but it can exacerbate environmental exposure to some contaminants.

For instance, lead — a neurotoxin prevalent in house dust and garden soils — enters children’s bodies most efficiently through ingestion and digestion.

More than 50 percent of people worldwide have headache disorders

So, you might worsen particular environmental toxic exposures if you sniff or eat boogers up instead of blowing them out.

What does the science say about the risks of booger-mining?

Golden staph (Staphylococcus aureus, sometimes shortened to S. aureus) is a germ that can cause a variety of mild to severe infections. Studies show it is often found in the nose (this is called nasal carriage).

One study found that nose picking is associated with S. aureus nasal carriage, meaning the role of nose picking in nasal carriage might be causal in certain cases. Overcoming the habit of nose picking might aid S. aureus decolonization strategies.

Nose picking might also be associated with an increased risk of golden staph transmission to wounds, where it poses a more serious risk.

Sometimes, antibiotics do not work on golden staph. One paper noted that growing antibiotic resistance calls for health-care providers to assess patients’ nose-picking habits and educate them on effective ways to prevent finger-to-nose practices.

Nose picking could also be a vehicle for transmission of Streptococcus pneumoniae, a common cause of pneumonia among other infections.

In other words, sticking a digit in your nose is a great way to jam germs further into your body or spread them around your environment with your snotty finger.

There is also the risk of gouging and abrasions inside the nostrils, which can allow pathogenic bacteria to invade your body. Compulsive nose picking to the point of self-harm is called rhinotillexomania.

Well, I picked. Now what?

Some people eat them (the technical term is mucophagy, meaning “mucus feeding”). Apart from booger eating being disgusting, it means ingesting all those inhaled mucus bound germs, toxic metals and environmental contaminants discussed earlier.

Others wipe them on the nearest item, a little gift to be discovered later by someone else. Gross, and a great way to spread germs.

Some more hygienic people use a tissue for retrieval, and dispose of it in a trash can or toilet afterward.

That’s probably among the least-worst options, if you really must pick your nose. Just make sure you wash your hands extra carefully after blowing or digging in your nose, given that until mucus has completely dried, infectious viruses can remain on the hands and fingers.

No advice in the world will keep you from digging away

In secret, in the car or on napkins, we all do it. And truth be told, it is so very satisfying.

But let’s honor the tireless labor done by our remarkable noses, mucus and sinus cavities — such amazing biological adaptations — and remember they’re trying hard to protect you.

Your snoz is working overtime to keep you healthy, so don’t make it any harder for it by jamming your grubby fingers up there. Don’t be a grub — blow discreetly, dispose of the tissue thoughtfully and wash hands afterward.
